Adding signals from two 33120A

There is an application note by Agilent, which describes how to add the signals from a waveform generator and a DC source, in order to get offsets up to 42 V (the limit for the 33120), by connecting them in series. In principle, this should work within the bandwidth of the DC source.
I tried this with two 33120 : one generating a sine, the other a DC voltage. The ac amplitude drops beyond about 100 kHz. Is this the limit from the 3310 bandwidth ?
